CRYPTOGAMIA. FUNGI. Agaricus, 
Bolt. 144. 
Stem cylindrical, solid, hollow with age. Curtain none. Gills narrow, brittle. 
Pileus at first convex, becoming horizontal, and lastly funnel-shaped, 
marked with darker concentric circles, but these are not always equally 
distinct, and in some plants hardly perceptible. Every part of it when 
wounded affords a copious discharge of yellow acrid juice. Bolt. p. 144. 
Stem solid, cylindrical, brown olive, blotched, two inches long, half to one 
inch diameter. Pileus always more or less hollowed in the middle, a 
little woolly, from three to five inches over. Specimen from Mr. Stack- 
house. 
Ag. pipera'tus. (Linn.) Gills pale, pinky red, numerous, in pairs; 
pileus dirty yellow white, woolly, depressed in the centre ; stem 
pale yellow. 
PI. Dan. 1068— Bull. Ag. necator, with no number to the plate , is a variety

turned down, and the centre depressed; three inches over. Flesh white. 
Stem solid, pale yellow, not central, nearly cylindrical, one and a half to two 
inches high, and half an inch diameter. Juice white, milky, very hot 
and biting.

Specimen, drawing, and description, sent to me by Mr. Stackhouse, who
